Characterization of rings with planar, toroidal or projective planar prime ideal sum graphs
Abstract
Let be a commutative ring with unity. The prime ideal sum graph of the ring is the simple undirected graph whose vertex set is the set of all nonzero proper ideals of and two distinct vertices and are adjacent if and only if is a prime ideal of . In this paper, we study some interplay between algebraic properties of rings and graph-theoretic properties of their prime ideal sum graphs. In this connection, we classify non-local commutative Artinian rings such that is of crosscap at most two. We prove that there does not exist a non-local commutative Artinian ring whose prime ideal sum graph is projective planar. Further, we classify non-local commutative Artinian rings of genus one prime ideal sum graphs.
